Kookaburras are terrestrial tree kingfishers of the genus ''Dacelo'' native to Australia and New Guinea, which grow to between in length. The name is a loanword from Wiradjuri ''guuguubarra'', onomatopoeic of its call. The single member of the genus ''Clytoceyx'' is commonly referred to as the shovel-billed kookaburra. The kookaburra's loud call sounds like echoing human laughter. They are found in habitats ranging from humid forest to arid savanna, as well as in suburban areas with tall trees or near running water. Even though they belong to the larger group known as "kingfishers", kookaburras are not closely associated with water. ==Classification and species== Four species of kookaburra can be found in Australia, New Guinea, and the Aru Islands. Kookaburras are sexually dimorphic. This is noticeable in the blue-winged and the rufous-bellied, where males have blue tails and females have reddish-brown tails. * Rufous-bellied kookaburra (''Dacelo gaudichaud''). (lowland New Guinea, Saibai island) * Spangled kookaburra (''Dacelo tyro''). (Aru Islands, southern New Guinea) * Blue-winged kookaburra (''Dacelo leachii''). (northern Australia, southern New Guinea) * Laughing kookaburra (''Dacelo novaeguineae''). (native to eastern Australia, introduced to southwest Australia) Unusually for close relatives, the laughing and blue-winged species are direct competitors in the area where their ranges now overlap. This suggests that these two species evolved in isolation (possibly during a period when Australia and New Guinea were more distantsee Australia-New Guinea. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「kookaburra」の詳細全文を読む スポンサード リンク
